As far as I know, this is one of the budget studio mics, and for me it works very well.
When I got it, I noticed that it has black spots and dots all over its body. I thought it's some kind of a defect, and contacted Thomann about it. They were about to change the item or provide a discount, while they got a note from AT that these dots and spots are fine. Even the image on AT site shows them (if you zoom in). So if you notice this, don't worry about them and enjoy the unit :-)
